Teelt @kunt it may y i i V i Beit known that "I, CHARLES W.3 COTTON, ofShelburneFalls, inthe county ofFranklin and State ofMassachusetts,`haveinventJ eda new and Improved Mode of Attaching x 4AugerstoI-Iandles; and I do herebydeclare thatthe following is ajlfull,clear, andexact description "of the sa-me," reference being .had

C to the Iannexed drawings, `making jpart of I this speciiicatiomiin L"f l* @F'gure l, isailongitudinal section 0f the center portion of anauger handle, the shank of theauger being secured thereto bymy improvedincide.;` `Eig."y `2,1is aftransverse section `ofzditto, the plane ofsectonbeing through` the center. `Fig".A 3, is` an "inverted plan or 1nSimilarletters of reference indicate corejspondingpartsfinftheseveralfigures.

The nature" foffmy" invention consists in `placing-a metallictubearoundthe center of the augerhandleand having a taper hole `madeentirelythroughzthehandle and tube 1 i inywhich hole the shank` of the auger is`yplaced. A metallicfhand iS-placedfaroundl the tube andworlsloosely onit, the shank l passing through Slots inthe band,.the lower i `slotbeingsomewhat taper `and"` its edges fit Iting in groovesin the,` sides 'ofthe shank `when the `band is"iturned, thereby` `securing theauger to thehandle.` y L A, represents the auger handle which may be constructed lofwood, and B, isthe metallicltube which is secured `on the handle at`about its center. y y center oflthejhandlevA, and tube` B, there ismadea taper hole "(ajfof rectangular form asclearlyshown in .,Figs; 1 and 2.Around `1 the center of the tube B, there is placeda metallic band C,which works between pins Transversely `through the Kb) .(22) see Figs.`1 and 3, said pins also i serving to secure the tube B, to the handleA.

The band "1C, is allowed to turnloosely onA the mbeB, andhas two slots(d) 'made through it at` oppositepoints, the slot (c) .f being,` oblongbut correspondinginwidth to p To enable others skilled theart to fully funderstand `and construct my invention, "I v will proceed to `describeit.

the upper part of the shank ofthe auger. The slot (d) is also oblong andone part of "it corresponds in width to the lower part of the shank andthe other part See (e) Fig. 3,

is oftaper `form and narrower than the shank. Y

D, is the shank of the auger of taper rectangular form corresponding insize to the hole (a) in the handle A. The lower part of theshank hasnotches or grooves (f) (f) in. it at opposite sides, see Figs. 1 and 2.

The Auger is secured to the handle in the following manner. The band C,is turned tillithe widest part of the slot (el) in the band iS directlyover the lower end of the hole (a.) in the handle A and tube B, and thei shank D, is then inserted in the hole (a), the

band C, is then turned and the edges of the taper `portion (e) of theSlot (d) lit in the notches orrecesses (f) (f) in thesides of the shankD, and ofcourse secure the auger to the handle. p l y The aboveimprovement is extremely Simple, and economical to manufacture, and

forms a secure fastening. And the augers mav be attached to or detachedfrom their `handles with the greatest facility.

What I claim as new and desire to secure by Letters Patent, is-

` `Attaching or securing augers `to handles l byhaving a metallictube B,placed around the center of the handleand having a transverserectangular taper hole (a) made through the handle and tube, and ametallic band C, placed around the tube B, and turning loosely thereon,said band having slots `(c) (CZ) made through it, a part of the slot l(d) beingoftaper form. The shank of the auger being placed in the hole`(0a) and through the slots (c) (al) in the band and `secured in thehandle by turning said band `and causing the edges of the taper portionof the slot (d) to pass in the notches or recesses (f) (7") in the shankas herein shown and described. i
